Normally these women are being used to sell things (e.g advertising) by some companies. They send these young sexy women to offices which have owners who are middle aged men. The women are fearless and try to find opportunities to be alone with the owners of the company so that they can convince them to sign up to something. It seems to work well with a lot of men who end up signing up to something and paying for something that they don't need. It won't work with men who do not lose their reasoning around these types.
